THREAD-CUTTING TEKVIPLE FOR LOOMZSJ Application filed October-9, 192 0.Serial no. 415,743.

a specification, like characters on the drawing representing like parts.

This invention relates to improvements in thread cutting temples forlooms and the object of the invention is to provide a con struction inwhich the journal pin for the temple roll does not extend across thepath of the cutter, and in which the selvage end of the temple roll isclosely adjacent to the cutter, thus to enable the cutter to operateclose to the selvage of the cloth.

The objectof the invention is secured by providing a thin separatingwall integral with the temple head between the cutter recess and theroll recess, which shall be sufficient to support and steady the selvageend of the roll pin and still permit the selvage end of the roll to beclosely adjacent to the cutter, and by supporting and securing the otherend 0 the roll pin, preferably by a threaded section, in the end wall ofthe head.

It the roll pin extends across the cutter recess it is a simple matterto support and secure the roll pin in position, but as the moving partswear the movable cutter blade not infrequently comes into contact withthe roll pin projecting across its path causing injury and damage toboth, and interfering with the accuracy of the operation of the device.If the separating wall between the cutter recess and the roll recess isprovided of a character sufficient to secure in position the roll pin itis necessarily of such thickness as to remove the selvage end of theroll a substantial distance from the cutter, which is undesirablebecause it interfere with the accurate cutting of the filling endsadjacent to the selvage of the cloth. In the present invention the rollpin is both supported and secured in position by the threaded connectionin the end of the temple head, while the selvage end of the roll pin issupported and steadied by a thin separating wall which still allows theselvage end of the roll to be closely adjacent to the temple cutter.

These and other objects of the invention will appear more fully from theaccom panying description and drawings and will beparticularly pointedout in the claims, In the drawings: 1 v l Figure l is a plan view of atemple em bodying a preferred form of the invention.

Figure 2 is an elevation of the construction shown in Fig. l. i t IFigure 3 is a vertical sectional view taken on line 3-3 of Fig.2. I

The general construction and purpose'of a temple and temple threadcutter for looms is so well known to those familiar with the weaving artthat it is unnecessary to set the same forth in anything more than ageneral way, t j I I These temples are mounted, usually on the breastbeam of the loom, one at each edge. of the cloth and act to stretch thecloth to and maintain it at the proper width while the temple threadcutters, associated therewith, act to sever close to the selvages thefilling ends extending therefrom.

The general construction of temple "and temple thread cutter illustratedin the drawings is of a familiar type, a temple for the ri ht hand sideof-the loom being shown.

The temple stand 1 which is bolted to the breast beam is shown partiallybroken away. The temple head2is carried bythe usual bar or shank 3slidable in the temple stand. This head 2 comprises a laterallyprojecting hollow cap l, and beneath a laterally projecting pod 5, thespace between the cap and the pod opening toward the center of the loom.The temple roll thus is journalled inithe recess 7 provided by thehollow cap, and is provided with some form of projections or teeth 8usually arranged in helical series about the periphery of the roll sothat as the cloth is fed during the weaving operation through thetemple, this roll acts to stretch the cloth toward the side of the loomupon which the temple is mounted.

The temple thread cutter is also shown as of a familiar type. Asillustrated it, comprises a fixed blade 9 mounted vertically in therecess 10, and a pair of movable blades 11 movable in the recess 10 andprojecting from a shank 12. The shank 12 is provided with the usualdepending heel 13, and is projected rearwardly by the usual spring 14.As the lay beats'up it strikes the heel 13 the head of the temple. Thisseparating wall is only of sufficient width and strength to support theselvage end of the roll pin 15, and consequently it enables the selvageend of the roll to be brought up closely adjacent to the cutter. Thisroll pin upon which the temple roll is journalled is supported at itsinner end in the end wall 16 of the head and it is entirely secured'inposition in this end wall. There is no objection to making the end wallof any desired thickness, and consequently a threaded section 17 orsubstantial length may be provided on the roll pin 15 and acorresponding threaded socket provided in the head end wall 16. It willbe seen therefore that when the roll pin 15 is in place it is securelyheld by the threaded engagement of the section 17 in the end wall 16,and that it is suiliciently supported and steadied atits selvage end bythe thin separating wall 14.

This temple roll is suitably journalled without the roll pin crossingthe path of the cutter, and at the same time the selvage end of the rollis closely adjacent to the cutter.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A thread cutting temple comprising a head having laterally adjacentcutter and roll recesses, the wall separating the said recesses and theend Wall of the roll recess both being integral with the head, a threadcutter mounted in the cutter recess, a temple roll mounted in the rollrecess, a roll pin extending through and journalling the temple roll,the said roll pin being terminally supported but not secured at itsselyage end in the supporting wall and the said Wall being of sufficientthickness only to serve as such support, the said roll pin at itsopposite end being supported and also se-' cured and held in position inthe end wall and the said end wall being of sufficient thickness toprovide the sole means for se curing and holding the roll pin inposition, whereby the integral separating wall is relatively so thin asto allow the selvage end of the temple roll to be closely adjacent tothe cutter.

2. A thread cutting temple having the construction defined in claim 1 inwhich the inner end of the roll pin is threaded and the end wall of thetemple head is correspondingly threaded removably to secure in positionthe roll pin.

In testimony whereof, I have signed my name to this specification.

ERNEST A. GAGNON.
